Create a deck built around an existing above-ground pool by specifying the part of the deck room occupied by the pool as 'Open Below'.
Create a polyline solid with a lattice material to go under a deck.
When a Deck room is created, the floor platform is modeled using joists, beams, posts, and planking as specified in the Deck Room Defaults dialog.
Automatic Deck Framing is a fast way to generate your decks' posts, beams, joists and planking. You can then modify any of these framing members as needed.
Deck planking is part of the structure and does not require a finish layer. When a floor finish layer is added to a Deck room a message will display.
